stuart_ashall Posted December 19, 2006 Share Posted December 19, 2006 This is my first post on this (or any) forum! I apologise if I'm repeating an earlier query but I can't see anything quite on this point... I have decided to go for a 5d. I have also decided to go for the "kit" lens 24- 105L which looks like a great all rounder. I also would want a wider angle lens to take full advantage of the full frame sensor. Question is which one? My budget will not stretch to 16-35L. I don't want a fisheye. I'm really looking at these two:- 1. 17-40L Pros - good build, sharp, same filter circ. as 24-105 Cons - only getting 7mm wider for my ?500! 2. Sigma 12-24 EX Pros - much wider, good build Cons - rear filter, where do I put my UV/polariser, heard its soft at the edges What should I go for or is there a lens I've missed? Any help or advice very gratefully recieved. Merry Christmas to you all, Stuart Link to comment Share on other sites More sharing options...
NK Guy Posted December 19, 2006 Share Posted December 19, 2006 17 to 24 mm doesn't sound like a big deal, but it represents a big difference in coverage area. I'd go to a local camera shop and try the lenses out to see. Link to comment Share on other sites More sharing options...
martin_howard1 Posted December 19, 2006 Share Posted December 19, 2006 17mm is pretty wide on a full frame camera - do you really want to go to 12mm? the distortion would be pretty overpowering for most subjects. I don't know much anout the sigma lens but I can say the 17-40mm is excellent. Link to comment Share on other sites More sharing options...
yakim_peled1 Posted December 19, 2006 Share Posted December 19, 2006 You need to think about FoV, not millimeters. The FoV difference between a 17mm and a 24mm is huge. The FoV difference between a 50mm and a 57mm is marginal. The FoV difference between a 100mm and a 107mm is almost invisible. The 17-40 will be wide enough on your 5D. 17mm in FF terms is ultra wide. Happy shooting, Yakim. Link to comment Share on other sites More sharing options...
colin carron Posted December 19, 2006 Share Posted December 19, 2006 I would recommend the 17-40L. I have owned both the lenses you are considering. The Sigma 12-24 while a good, sharp lens is quite a bit bigger than the Canon and has a very vulnerable bulbous front element. It is very difficult to make filters work with it especially on full frame. In the end I used big square filters held in front of the lens - not ideal. The Canon 17-40L is also a good, sharp lens. It is smaller and much more manageable for filters such as the polariser or UV. As far as the 12mm to 17mm range goes I think you would find the perspective at the ultrawide end is rather gimmicky and wild. The overlap of the focal lengths will not go to waste entirely as it will save you having to chnage lenses so often - a consideration with the rather dust-spot prone 5D. (Don't get me wrong the 5D is a superb camera) Link to comment Share on other sites More sharing options...
mark u Posted December 19, 2006 Share Posted December 19, 2006 This review of the Sigma 12-24 includes some examples of its use on full frame: http://www.prime-junta.net/pont/Reviews/a_Sigma_12-24_f4.5-5.6/a_Sigma_EX_12-24_f4.5-5.6.html At 17mm, you get just over 90 degrees horizontal field of view, and at 12mm you get 90 degrees of vertical field of view - use this calculator to get an impression of what that implies: http://www.eosdoc.com/manuals/?q=jlcalc Link to comment Share on other sites More sharing options...
mvw photo Posted December 19, 2006 Share Posted December 19, 2006 Fwiw, I have the 17-40 4L (as well as the 50 prime, 70-200 4L and 24-70 2.8L) and that 17-40 is great. <p> <a href="http://www.willems.ca/gallery/albums/userpics/10001/barrel.jpg">Example here, at 40mm</a><p> <a href="http://www.willems.ca/gallery/albums/userpics/10001/IMG_1666_small.JPG">Example at 17mm</a><p> <a href="http://www.willems.ca/gallery/albums/userpics/10001/IMG_1721_small.jpg">Another at 17, showing how accurate it is</a><p> Hope that helps -Michael Link to comment Share on other sites More sharing options...
jcraig Posted December 19, 2006 Share Posted December 19, 2006 One more plug for the 17-40L, and also note that due to the overlap of some of the FL range using this lens with your 24-105, will lead to you needing far fewer lens swaps than if you were to go with the 12-24. You'll come to appreciate this... Link to comment Share on other sites More sharing options...
roger pfister Posted December 19, 2006 Share Posted December 19, 2006 I got the 5D with the 24-105 and the 17-40. I have the Sigma 12-24 which I got when it came out to go on my 300D. You want to the 17-40. I never bother to mount the 12-24 on the 5D. It just never happens. These days I tend to got out with the 5D 17-24 and a A710IS in my pocket for longer shots (I am not much of a long shooter). -- Roger Link to comment Share on other sites More sharing options...
lovcom_photo Posted December 19, 2006 Share Posted December 19, 2006 Save your money and get the 16-35L. It's just another $600 over the 17-40L. If you can afford a 5D you can wait a little longer and do it right. Slow lenses are a waste on such a fine DSLR. Better to get the F2.8. Delayed Gratification is in order.

mvw photo Posted December 19, 2006 Share Posted December 19, 2006 Ah, but "only" another $600 is a personal assessment.. hold for you no doubt, but I don't feel there's an "only" there... $600 is a lot of money. And the F4 will do almost everything the 2.8 does. One stop is not that big a deal! Link to comment Share on other sites More sharing options...
KenPapai Posted December 19, 2006 Share Posted December 19, 2006 Do save your money and get Canon's highest quality UWA zoom for your 5D (the aforementioned 16-35). You'll be VERY happy you did; you owe yourself *at least* one fast lens (Canon lingo: "fast means f/2.8 or wider) for your 5D. There are no downsides to that lens and no serious competition either. You need just one filter, a thin circular polarizer; if you feel paranoid then also get a UV filter for front element protection. Link to comment Share on other sites More sharing options...

But I use the 17-40 4L and the 70-200 4L a <i>lot</i> more. So is it worth $600 more to have the wide 2.8? I';d personally put that towards the 24-70. Your mileage may vary - just what works for me.

ameripol Posted December 19, 2006 Share Posted December 19, 2006 I love my 16-35 so much, I refer to it as 'Mr." It's super and worth every penny if you need the speed. However, digital allows ISO change on the fly and maybe the 17-40, a a lower cost, is all you'll ever need. I would not look at any other lenses for a wide zoom need.

w_t1 Posted December 19, 2006 Share Posted December 19, 2006 that 17mm shot of "1666" is neat. What and where (GB?) is that facility, or is that a manipulated photo? It almost looks like a doll house set. I love my 17mm, wish it was po$$ible to make a shift 17mm Link to comment Share on other sites More sharing options...
mvw photo Posted December 19, 2006 Share Posted December 19, 2006 Thanks. No manipulation: Absolutely real and 'as seen'. This is the Great Hall of the British Museum, in London. I am there a lot and usually make it to the Museum. That 17-40mm lens is very good for these types of shot. Michael Link to comment Share on other sites More sharing options...
russ_savage Posted December 19, 2006 Share Posted December 19, 2006 first, this has been discussed at length on multiple forums. But, to oblige you, I'm going to have to be honest and disagree with the majority of posters here. The 17-40 is not a High Quality UWA. It suffers from some serious problems. Distortion, vignetting, corner sharpness, loss of contrast in the corners. and all of these are noticeable on the 5d. I'd suggest the 16-35 as I've heard it is quite good, but ultimately even that, canon's flagship UWA is inferior when compared to zeiss, olympus, and nikon wide primes. If you need zooms and AF, by all means get the 17-40 or save for the 16-35. but ultimately I opted for a 21mm and 18mm zeiss and olympus combo. each of which could be found for roughly 700 including adapter. And both clearly beat any canon wide offerings. best wishes. rSavage Link to comment Share on other sites More sharing options...
fourfa Posted December 19, 2006 Share Posted December 19, 2006 "do you really want to go to 12mm? the distortion would be pretty overpowering for most subjects." it pays to be precise here. In terms of the traditional definition of distortion - rendering parallel lines as parallel - the 17-40 has somewhat bad distortion, and the Sigma is the best performing UWA zoom available. The Sigma 12-24 is sometimes referred to as "the architectural photographer's friend" for that reason alone, completely beside the fact that it goes to 12mm FF for interiors. I suspect what you meant instead is "perspective convergence," where vertical lines lean inward as you tilt the camera upward. It can be difficult to use a 12mm FF field of view, though no doubt all of us have seen architectural interior photos done skillfully with this lens and never even realized it. Successful outdoors and landscape photography with 12mm FF is quite a bit more rare. I'd wager that an event photographer could put it to good use though, given enough light. However I'd agree that for a general purpose all-arounder for a FF camera, the 12-24 is a bit unique and specialized and the 17-40 is pretty great.

dan_vidal Posted December 19, 2006 Share Posted December 19, 2006 The wonderful thing about having a full-frame DSLR is that you get your wide angles back that those of us in 1.6 land sorely miss sometimes. I second the suggestion that you save your cash for the 16-35 2.8L. The extra stop is worth it, and the sharpness of this lens is superb, probably amongst the best I've seen on any Canon lens. I hire one occasionally for my 30D, and the results are phenomenal. I would buy one, but I do a lot of low-light shooting, and the lack of a stabilizer made me decide in another direction (EF-S 17-55 2.8), but since it is EF-S, it doesn't apply to your situation. Actually, what I'd suggest while you're waiting is to find a local rental shop and hire the lens when you specifically need it, until you are able to buy it. On a camera such as the 5D, I wouldn't really consider third-party lenses. The quality of the files this camera generates can only be properly exploited by genuine Canon glass.

dave chew Posted December 19, 2006 Share Posted December 19, 2006 Why not a 20mm prime? You are already getting down to 24mm with the L, although I admit it does vignette substantially at that focal length. It's much more in line with your budget. I wouldn't worry about your polariser too much. At that wide angle you'll get a dramatically different effect across the frame, so I'm not sure you would like the results anyway.

john_kramer3 Posted December 19, 2006 Share Posted December 19, 2006 I agree with the other posters. I made the same decision a half year ago and bought the 17-40, and it is by far my favorite lens to use. However, I would trade anything to make it a 16-35. If it's at all possible, do it. you're going to want to upgrade it sooner or later. f/4 just sucks. Link to comment Share on other sites More sharing options...
mvw photo Posted December 19, 2006 Share Posted December 19, 2006 Yes, and maybe one day I will upgrade too - but surely in the mean time the 17-40 performance as evidenced by my examples above is pretty great? Sharp, and negligible distortion and vignetting. So I would urge those of you deciding not to read too much into those issues. Link to comment Share on other sites More sharing options...

dogbert Posted December 20, 2006 Share Posted December 20, 2006 Having owned the Sigma 12-24 I found it to be a pretty good lens. Build quality is very good. It is big and heavy, but probably no more inconvenient to carry around than a 75-300 zoom. The bulbous front element looks somewhat vulnerable, but in practice I never found it to be a problem at all. It is actually below the metal rim/fixed hood so is quite well protected. The HSM worked well, and is about as good as canon's USM. You can forget pretty much using filters with this lens. 85mm filters can be screwed into the two part lens cap if needed but you will get vignetting at 12 mm. Colour and contrast were fairly good, sharpness was ok stopped down but a bit below other lenses I have used. While it stands up to 8x10 prints they won't be exceptionally sharp. I used it on a 300D and on a film body. However, in practice it was almost impossible to come up with a good composition at 12 mm on a FF body. If I were looking for an ultrawide on the 5D, I think the 17-40 would be my first choice. 17 mm is plenty wide on FF. Link to comment Share on other sites More sharing options...
dogbert Posted December 20, 2006 Share Posted December 20, 2006 On the other hand, with the 17-40 you'll be just like everyone else. If you can pull of some good shots with a 12mm lens you will be pretty much unique. I wasn't capable of this. Link to comment Share on other sites More sharing options...
